Document DEVICE REPORT2DatasheetLE300enLITHIUM EXTENSION BATTERY LE300 EXTEND ANY LEAD ACID BATTERY SYSTEM WITH LiFePO4 HYBRID TECHNOLOGY THE LE300 LITHIUM EXTENSION BATTERY IS A FULLY SCALABLE SOLUTION TO ENHANCE PERFORMANCE AND ADD CAPACITY TO LEAD ACID BATTERIES IN SOLAR AND ANY OTHER KIND OF ENERGY STORAGE SYSTEMS. THEY CAN BE USED WITH NEW OR EXISTING 12 V LEAD ACID BATTERIES. JUST STACK THEM IN PARALLEL TO MEET YOUR SPECIFIC SYSTEM SPECS. Like in all BOS AG Hybrid battery systems the LE300 Lithium Extension Battery takes most of the charging cycles while the lead acid battery provides inexpensive backup capacity. The lead acid battery is charged with higher priority, the LE300 Lithium Extension Battery takes all surplus energy. This helps to increase the lead acid battery life. The system recognizes the lead acid battery voltage and automatically starts to support the lead acid battery with a maximum current of 12.5 A per unit. Bigger loads get supplied by the lead acid and the lithium battery in parallel, resulting in smaller currents for each battery. CORE BENEFITS · Flexible capacities by simply connecting several packs · State of the art LiFePO4 batteries · Retrofitting & extension of already installed systems without change in wiring or other components · No additional controller needed, simply connect directly to the lead acid batteries · Lead acid battery is charged with higher priority, lithium battery is discharged first · Lithium performance and lead acid cost advantages are combined · Plug & Play > simply connect two cables · Robust housing with variable fixing possibilities · Integrated heating for low temperature charging BOS BALANCE OF STORAGE SYSTEMS AG / BOETTGERSTRASSE 2/2 / 89231 NEU-ULM / GERMANY / FON: +49 (0) 731 72 54 41 07 / MAIL: [email protected] / WEB: WWW.BOS-AG.COM LITHIUM EXTENSION BATTERY LE300 EXTEND ANY LEAD ACID BATTERY SYSTEM WITH LiFePO4 HYBRID TECHNOLOGY System voltage Nominal voltage Voltage range Battery packs used in LE300 Nominal lithium capacity Usable lithium capacity Numbers of cycles at room temperature Recommended lead acid capacity for each LE300 (not included) Recommended lithium/lead acid capacity ratio (net) Continuos charging/discharign current Battery efficiency Housing dimensions Weight Connection terminals Recommended wire size Ambient temp.

Warehousing temperature 10 30 °C. Temp. sensor prevents lithium battery charge under -5 °C or above 55 °C cell temp. Charging starts once cell temp. is higher than -5 °C. Device has an integrated heating that is active between -20 °C and 10 °C cell temp. Discharge possible between -20 °C and 60 °C cell temp. At cell temp. below -20 °C and over 60 °C system is running in pure lead acid mode for higher battery lifetime. Battery management inclusive balancer Overcurrent, overvoltage, short circuit, deep discharge, wrong polarity protection. Works in combination with any 12 V lead acid battery & lead acid charge controller. In standard version, a maximum of 24 LE300 can be connected in parallel, higher quantities possible after consulting BOS partner.
